Each paper sorted into one sub-area by an AI model reading its title and abstract, then credited as usual. On 200 hand-labelled papers it chose the same sub-area, or a defensible second, 92% of the time. Shown where the sub-area has at least 30 papers in the top 10% and the country at least five papers of credit.
